Python library to retrieve observations and forecasts from NWS/NOAA

Project description

pynws

A python library to asynchronously retrieve weather observation from NWS/NOAA.

Example

See example.py for a runnable example.

PHILLY = (39.95, -75.16)
USERID = "testing@address.xyz"

async def example():
    async with aiohttp.ClientSession() as session:
        nws = pynws.SimpleNWS(*PHILLY, USERID, session)
        await nws.set_station()
        await nws.update_observation()
        await nws.update_forecast()
        await nws.update_alerts_forecast_zone()
        print(nws.observation)
        print(nws.forecast[0])
        print(nws.alerts_forecast_zone)

Functionality

pynws exposes the ability to retrieve raw data using raw_data module. Nws class offers ability to retrieve minimally processed data for a single location. SimpleNWS class offers data caching and several other helpers for interpreting output.

Units for Observations in SimpleNWS

NWS API does not expose all possible units for observations. Known units are converted to the following:

unit type known NWS units pynws unit
temperature degF, degC Celsius
pressure Pa Pascal
speed m_s-1, km_h-1 km_h-1
percent percent percent
angle degree_(angle) degrees
distance m meter
